APPARATUS FOR MAKING COKE AND GAS.

ll ,otonoo.

To 14H w/m'm/ it may] concern lie it known that I, \ViLLIAM M; CARR, a citizen of the United States, residing at Wheeling, in the county of Ohio and State of Vest Virginia, have invented certain new and useful Improvements in Apparatus for making Coke and Gas, of which the following is a SPGClfiCzLtlOll.

This invention relates to apparatus for making coke and gas; and it comprises stationary regeneratively operated firing means having oppositely located firing ports spaced away from each other, means for successively introducing a plurality of transport able firing chambers between and in engagement with saidfiring ports, each such firing chamber being adapted for ready engage-' ment. and disengagement with such ports and beingprovided with a contained closable coking and gas-forming chamber or retort, and a stationary gas-removing conduit adapted to be made to engage with such retorts successively as the cbrresponding inclosing fire chamber comes into register with such firing ports; all as more fully herein-' after set forth and as claimed.

For a number of reasons the continuous manufacture of satisfactory coke is somewhat difiicult in practice. WVhere itis'attempted to pass coal as a continuous prism or stream through a heating chamber, the resulting coke is inevitably more or-less crushed and disintegrated. The cooling of the incandescent coke coming from such a chamber is furthermore a difficult and unpleasant operation. It is usually done by quenching with water which causes the generation of clouds of steam and usually results in a wet coke which requires re-drying. The discontinuous coke-makingoperations give better coke but are relatively slow, since the operator must wait for the heating up and cooling of the furnace chambers, rctorts, or ovens. As concerns the gas making operation in the discontinuous processes, the'gas is necessarily of different qualities at different stages in the operation, and the larger the mass of coal so treated the greater, of course, is the volume of gas of special quality given off at any special stage in the operation.

In the present invention I have devised a new type of apparatus for the'manufacture of gas and coke c mbining the advantages of the continuous and discontinuous operations. In this apparatus, the operation is Specification of Letters Patent.

continuous as regards .the firing means but is discontinuous as regards the particular portion of coal at any time under treatment, successive relatively small portions of coal being treated by continuously operating firing and gas removing means. The coal is not handled or moved during its conversion into coke -and therefore suffers a minimum of disintegration; and it is cooled in the apparatus in which it is made, thereby avoiding the necessity for quenching. As many relatively small portions of coal as ma'y be desired may be under treatment at once in different stages of the operation, thereby equalizing the quality of the gas which is given 01f. I

In the present invention I provide a plurality of transportable coking chambers, each being provided with an individual firing chamber. These firing chambers are provided with ports or openings adapted for engagement with firing ports of a regeneratively operating heating apparatus. These firing ports may communicate with the usual checkerworks and are so spaced apa'rt'that firing chambers may be brought between them and into engagement with such ports. Advantageously, there is a line of rails between the spaced firing ports on which may travel trucks carrying one or more firing chambers. Each such firing chamber has Within it a closable or closed retort. cated above the regenerative firing means is a stationary gas removing means and meansfor connecting it successively to each of the coking chambers temporarily under treatment. Where the firing chambers are carried, as is usually the case, on trucks, a coking chamber may be loaded with coal and a truck pushed forward until the ports of the firing chamber make engagement with the corresponding spaced ports ot'the regeneratively heatedapparatus, and the gas removing means brought into engagement with the retort. Firing is now proceeded with until the contents of the retort are coked to the degree desired when the firing chamber and contained retort are pushed forward by moving the truck, the gas removing means being disengagd and the top closed with any suitable closure. The contents of the' retort may nowbe allowed to cool spontaneously. As the chamber containing the finished coke are removed fnom the regenerative firing device another firing chamber with a retort carry retort and Of course more than one regenerative apparatus may be provided; and where such is the case, a plurality of regenerative firing devices may be simultaneously treating a plurality of coking retorts in different stages 'of the operation, the gas from each such coking retort being delivered to a suitable main. This averages out the temporary fluctuations in the quality of the gas. But of coursewith a single regenerative firing device, the gas coming from all theretorts may be delivered into a common collecting chamber or gasometer and the fluctuations in the quality of the gas thereby averaged out.

In thenccompanying illustration I have shown, more or less diagrammatically, certain embodiments of the described invention. In this showing, Figure 1 is a side elevation of a complete installation showing two of the combined firing chambers and re torts, one such chamber being in operative position and the other awaiting engagement; Fig. 2 is a vertical elevation seen from one end of the apparatus; and Fig. 3 is a vertical section on an enlarged scale of one of the combined firing chambers and retorts described.

In the showing of Fig. 1, element 1 is a regenerator of a common type connecting with stack 2; Air ports 3 may lead up from this regenerative structure intoengagement with the firing chamber. As shown the regenerator may only deliver hot air, the necessary combustible, such as oil or gas, being introduced through ports 4. Mounted on a truck 5 running on wheels 6 and track 7 are shown two of the combined firing chambers and retort-s, respectively 7 and 7, the latter being shown 1n engagement with regenerative firing means while theformer is awaiting engagement. Both are provided with opposite open flame ports 8 adapted to engage the firing ports of the regenerative de vice. Each is shown as mounted on standards 9 having means for tilting, 10. This is convenient in emptying the retorts. The top of the retort in operation delivers its gas through connection 11 valved at 12 to main 13.

Referring now to Fig. 2, the elements justdescribed are designated by the same reference characters. In addition there is shown elevating means 14 engaging the cover or top and adjustable connection 15 for the gas removing means. car 17 adapted for supplying fresh coal to the retorts. .Cars 18 may be used for removing the cooled coke.

On platform' 16 is shown In Fig. 3 is shown the combined firing chamber and retort on a larger scale; As there shown, 19 is a fire chamber of any" suitable refractory material in a steel shell 20.

The open ports previously referred to, provide for transverse passage of flame through the chamber. Within the firing chamber is a retort or container 21 of iron, clay or anyother suitable material supported on blocks 22 and having an open top registering with the open top of the firing chamber, As shown, the latter open top is provided. with a coned opening 23 within which rests a cap 24 of any suitable material provided with lifting lugs 25. This cap is centrally provided with a coned opening 26 having an offset 27 within which agasket 23 of asbestos rope or the like may be located. Resting within this coned opening is a disengageable water sealed apparatus 29, having a coned lower end adapted to enter t e opening and remove the gases, and having at its upper end a depending wall 30 adapted to enter within a trough formed by an upward prolongation 81 of the gas 'con nection (11) previously referred to. This device may be used as a water seal. As will be seen, the cap may be readily lifted into and out of engagement with the gas connection.

The operation of this structure is be lieved to be obvious from the foregoing.

The re enerative devices (1) being in operation, flames sweep across the firing chamber '(T temporarily in operation, alternately passing in each direction in a well understood way. The coal coking in the retort chamber 21 gives off its gas, which passes through 11 and 13 to a place of use (not shown), being scrubbed and purified'in the usual way. When the evolution of gas ceases and the coking operation is carried as far as may be desired, element 29 is lifted by let out of the way and a temporary closure is placed in the opening in the cap of the firing chamber. The firing chamber may now be run oif and the contents of the retort allowed to cool naturally. The next retort" in order (7 having been filled with coal from 17, is run into place in engagement with the ports of the regenerative heating device, water seal 29 is lowered into place and the operation is repeated. Gas from 13 may be supplied through 4 to the firing ports- What I claim is 1. In apparatus for making-gas and coke,
